Abstract: Pulse combustion is known to offer better energy efficiency and low pollutant emission relative to steady combustion. Conventional cylindrical geometries are not the only ones that can be used for gas-fried pulse combustors although conventionally this is the practice. Some novel concepts such as use of a "heart" shape combustion chamber, fractional and spiral tailpipes, etc can be potential design innovations. They are simulated using a CFD model that was validated earlier with published experimental data. It was found that some potential geometries can achieve steady pulse combustion. Operational characteristics such as the specific impulse, thrust output-to-power input ratio, etc are computed and compared. Such studies are expected to yield better designs of the pulse combustor leading to more industrial applications in future.
